8.2: How come exec() doesn't return?

(contributed by brian d foy)

The "exec" function's job is to turn your process into another command
and never to return. If that's not what you want to do, don't use

If you want to run an external command and still keep your Perl process
going, look at a piped "open", "fork", or "system".


The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
